Mozilla IT & Operations

We will have a scheduled maintenance window Thursday night from 7:00pm – 11:00pm PST (0300 – 0700 UTC). The following changes will take place:

7:00pm – We will be replacing a faulty midplane on a blade chassis containing 14 servers which support the following services: addons.mozilla.org, download.mozilla.org, crash-stats.mozilla.com. With the exception of crash-stats, the affected servers are all redundant or non-production, and therefore no actual downtime is expected. crash-stats will still be working, however status pages will not update for the duration of the window.(canceled due to schedule conflict, will reschedule at a later date)

8:00pm – We will be reverting to a previous version of the DAHDI drivers for our telephone interface cards on the phone server in Mountain View in order to avoid a kernel panic that’s been happening frequently with the current version. Expected downtime is about 10 minutes.

Please let us know if you have any reason why we should not proceed with this planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window.

Feel free to comment directly in those bug (or this blog) if you see issues past the planned downtime.
